Hi,
WHen you did this, did you:
A) Start the engine while the 50AMP charger is still connected and charging
or
B) Connect the 50 AMP charger, wait few mins, disconnect the 50 AMP charger then start the engine
Thanks. |
I did "B". I have a gauge on the charger...and when using the 50 amp "boost charge" I leave it connected until the gauge registers it's okay. Then I removed the charger from the battery posts before starting the car.
Unless you're really committed to buying only BMW or MB batteries...you can use just about any 49/H8 or 95R/H9 class size battery. Most battery brands in the USA are made by the same 3 battery manufacturers (Johnson Controls, Exide, East Penn). You can see in the chart below what the specs are for the East Penn
49/H8 & 95R/H9 batteries are. The ones mfg'd by JC & Exide have pretty similar specs. The warranties may vary by brand label...but again, are usually 2 or 3 years...many times with an extended pro-rated warranty after the initial full replacement years.
I've always suggested checking your local autoparts stores like Autozone Advanced Auto, O'Reillys, Pep Boys etc...then there's Batteries Plus, Sears, Walmart, Interstate Battery outlets/stores, etc. Again, your looking for the
49/H8 or 95R/H9 battery class size. This will be the equivalent of the usually $200+ BMW branded battery. You can also decide if you want lead acid or AGM...either will still need to be vented (so be careful not to lose or pull the X5's vent tube out...you'll need to reuse it and the little elbow).
Here's some examples of replacements:
